Saito has tested positive for acetalozamide, a diuretic that is also a masking agent which can disguise the use of other banned substances. The Court of Arbitration for Sport says Saito "accepted on a voluntary basis to be provisionally suspended and to leave the Olympic Village." He did not race in any event before the test result from a pre-competition sample was confirmed. (AP Photo/Kerstin Joensson, File)
